Chapter 8 Flashcards
Temperature
A measure of how hot or cold something is; specifically a measure of the average kinetic energy of the particles in an object
Thermal Expansion
An increase in the size of a substance in response to an increase in the temperature of the substance
Absolute Zero
The temperature at which molecular energy is at a minimum
Heat
The energy transferred between objects that are at different temperatures
Thermal Energy
The kinetic energy of a substance’s atoms
Thermal Conduction
the transfer of energy as heat through a material
Thermal Conductor
A material through which energy can be transferred as heat
Thermal insulator
A material that reduces or prevents the transfer of heat
Convection
The transfer of thermal energy by the circulation or movement of a liquid or gas
Radiation
The transfer of energy as electromagnetic waves
Specific Heat
The quantity of heat required to raise a unit mass of homogeneous material 1K or 1C in a specified way given constant pressure and volume
States of Matter
The physical forms of matter, which include solid, liquid, and gas
Change of State
The change of a substance from one physical state to another
Insulation
a substance tht reduces the transfer of electricity, heat, or sound
Heat engine
A machine that transforms heat into mechanical energy or work
